Solar energy prices have fallen 80% in recent years and its usage continues to rise as the utility companies raise their rates.

So, what are you waiting for?

Break free from your electric company and start saving with Semper Solaris solar energy.

Our Military Roots

Co Founder Kelly Shawhan and family

As a Captain in the US Marine Corps trust means everything. Trust, to be there for my Marines. Trust, to be the expert. Trust, to get the job done right. That same philosophy stayed with me for the past 20 years as a contractor and a solar specialist. Solar can be complicated, but at Semper Solaris we pride ourselves on taking the time to help you understand how solar works and how to choose the right system. Find out why homeowners all over San Diego trust Semper Solaris.

Solar power is all about the freedom to afford to run your AC. We make solar simple, stripped of hype, high pressure and high prices, the basic reality of solar electricity is simple. It’s a math problem, with an obvious answer. No land needs to be bought or leased, as it is already present. No additional infrastructure needs to be installed, as the home wiring is generally sufficient and the home is already tied into the grid. With current prices as low as they are, there will likely never be a better time to go solar.
-John Almond
Co-founder, Semper Solaris

    After spending weeks of searching and reading customer reviews for a reputable solar company, we went with Semper Solaris. Sempers customer review history carried a lot of weight with us, and proved to be a very positive experience as written in all of the previous customer reviews we read everywhere online. The product speaks for itself, SunPower panels with Maxion technology, need I say more, they use only the best panels on the market. The Power inverter they use and installed is the SolarEdge unit, again only the best in product quailty, reliability, and warranty. We love that piece of mind knowing things will last, and are backed up. It was fairly simple to get to thru the whole experience, because Semper has a team of impressive leaders. Ours was handled personally by Semper's Customer Specialist Kristine Hanks. This professional young lady never left our side. Kristine was there to answer our questions every time we didn't understand something in the process. Who does that in today's world of business! Semper Solaris does.

    Nothing more to really say, but the company is great! I had some unfortunate events happen with my old solar company going out of business and leaving me hanging with a few small issues. I called around to a couple places and Semper was the most helpful, they listened, and worked with me. They came out the next day and everything appears to be up 100%. Greatly appreciate all that they have done!
